Electric opening rooflights in Dulwich: what is involved?
Electric opening rooflights in Dulwich means hinged rooflights that open on an electric actuator for fresh air. We cover the SE21 district and the rest of Greater London, with a survey before any price is fixed.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Think of electric opening rooflights for kitchens, bathrooms and bedrooms that need fresh air as well as light.
Dulwich is around 7 km from central London, and we survey and fit throughout that part of Greater London, including the SE21 district.

Do you need permission in Dulwich?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about electric opening rooflights in Dulwich
Is it noisy?
Actuators run for a few seconds and are about as loud as an electric blind. Once closed, an opening unit is as quiet as a fixed one.
Can I control it from my phone?
Some ranges link to smart-home hubs or their own app. If that matters, say so at survey and we will specify a compatible model.
Can it open in a power cut?
Most electric units stay where they are during a power cut. Some manufacturers offer a manual override or battery backup — we will tell you which option the chosen model has.
Will I need planning permission in Dulwich?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line.
Do I need to be at home for the survey in Dulwich?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
